. D was n ERQ EE 0 EAYETTEVILLE sam s esb AcETYn n -eas ennn mrr oitq vTo all whom/it may concern Be it known that I, ROY BERCHEEN, a citizenof the United States, residing at Fayetteville, in the county of Lincolnand State of Tennessee, have invented new and useful Improvements inAcetylene-Gas Generators, of which the following is a Specification.

The invention relates to acetylene gas generators; and has for itsobject to providea generator of this character wherein the gas-' ometeror bell-is formed with a water displacerwhich serves to lift the watertothe carbid holder or container which ishofthe collapsible type toallowit to be readily and easily cleaned when the same is to be refilled withcarbid, the gasometer or bell being of novel form to insure the perfectworking of the generator.

Another object of the invention is the provision of a generator of thischaracter wherein the gas service pipe has one stretch thereof arrangedwithin the water tank and is inclosed in a jacket so as to avoid thepossibility of the sweating of'the said stretch o.

of the pipe when the generatoris in action, thus the said stretch of thep pe will be rendered perfectly dry at all times.

A further object of the invention is the provision of a generator ofthis character wherein the service pipe'hastapped therein a filter whichremoves all sediment or foreign matter from the gas flowing there;-

through, thepoint of connection'of the service pipe with the filterbeing above the bot: tom of the latter, so that the sediment and foreignmatter collected therein will not interfere with the free flowing of gasthrough the service pipe, thereby avoiding any possibility of thechoking up of the burners at the points of illumination of the gas fromthe service pipe.

A still further objectof theinventio-n is the provision of a generatorof this character known generally as the floating gasometer type havinga dip carbid container or holderpossessing simplicity, efficiency anddurability, also one whichmay be manufactured at a minimum expense.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawing'andpointed out in the claims hereunto appended.

In the drawing :Figure 1 is a vertical ste fi t m nt- Patented Nov.='2,1915.

Referring to the drawing in detail, the I is of uniform cross sectionalsize, while the i'emainingupper portion is contracted as at and'has anupperopen end 11. The top' 12 of the gasometer or bell is extendedwithin the contracted portion-10 and has rising centrally therefromacolumn 13 forming be- 7 tween; it and the contractedwall 10 a waterspace 14: which extends concentrically about thecolumn 1'3. Dependingfrom the top 12 of the bell or 'ga'sorneter9 is the: extended tubularportion of a hollow cylindricalfloat 16 forming a water displacerworking within the inner water tank 7 for lifting thewater 7 into thecolumn on the lowering of the gasometer or bell 9 within the outerwater't'ank 5 of the generator. Detachably telescoped cally about thecolumn 13. The.water when placed within the said space'li'acts asa waterseal between the column 13 rand-the over the upper end of the column 13,so as to extend Within the water space ltconcentriflange 18 on the capwhile the water when placed within the space 18 serves as a water sealbetween the'bell or gasometer'9 andthe' inner watertank 7, the tubularportion 15 being formed with a series of perforations 19.

to permit the passage'of gas from-the space above the Water displacer orfloat 16into the. upper portion of the bell or gasometer 9 above thewater level therein; a 1 Removably fitted within thecentral open: ing orborein the water displacer or float 16' is a carbid container or holdercomprising a cylindrical body 20 having an inturned annular flange 21 atits lower edge and in this body is slidably fitted a cup-shaped bottomsection 22, the same being formed with an outturned annular flange 23 atits upper free edge to engage and rest upon the flange 21 on the body20, thus the said carbid holder can be collapsed or extended, therebyenabling the convenient and easy cleaning of the same when refilling itwith a charge of carbid. Swingingly connected to the body 20 is ahand-bail 24 which permits the convenientremoval of the carbid containeror holder from the generator or the placing of the same therein. Risingcentrally from the bottom section 22 is a reticulated or foraminous tube25 which permits the entrance of water from the inner tank 7 on thelifting thereof by the water displacer or float 16 into the carbidcontainer or holder, so that the carbid therein will be commingled withthe water for the production of gas which fills the column 13 and isdischarged through the perforations 19 into the hell or gasometer whichrises under the pressure thereof.

Mounted on the outer side of the body 20 of the carbid container orholder are bearings 26 which engage with the upper end of the float 16for the holding of the carbid container or holder within the centralopening or bore therein.

Mounted exteriorly on the contracted portion 10 of the gasometer or bell9 are reversely disposed hooks 27, while mounted on the top of the capis a bail 28 forming a handle having laterally extended ends 29 whichserve as keepers to engage the hook 27 and thereby lock the cap inposition for closing the upper open end of the gaso-meter or bell.Tapped centrally in the top of the cap 17 is a valve or blow-off cook30, while rising from the said top of the cap near the marginal orperipheral edge thereof is a safety spout 31, which is of the ordinarywell known construction.

Extending from the outer tank 5 is a water drain pipe 32 and likewiseextending from the inner tank 7 through the outer tank 5 is a waterdrain pipe 33, so that the water in both of these tanks can be readilydrained therefrom as the occasion may require. Rising within the waterspace 8 between the outer and inner tanks 5 and 7 is a vertical stretchof a gas service pipe 3%, which is held fixed in any suitable manner andis extended through the outer tank 5 withoutthe same and has connectionwith a gas filter 35 at a point above the lower end thereof which servesto collect all sediment and foreign matter, and by reason of the pointof connection of the pipe 34 with the said filter 35 the service pipewill be prevented from choking or stopping up. The gas passing throughthe filter 35 is distributed to any desirable point in the usual wellknown manner for illuminating purposes.

Surrounding the vertical stretch of the service pipe 3 and within thewater space 8 is a tubular jacket 36, which is spaced from the said pipeand is closed at opposite ends so as to prevent the sweating of thevertical portion ofthe said pipe 84 and thereby maintain the sameconstantly dry.

From the foregoing it is thought that the construction and manner ofoperation of the device will be clearly understood, and therefore a moreextended explanation has been omitted.

What is claimed is 1. A generator of the class described comprising anouter water tank, an inner water tank therein rising from its bottom, agas bell working between the outer and inner water tanks and having acontracted upper portion, a column rising from the top of the bellcentrally within the contracted portion, a water float depending fromand centrally within the bell and working within the inner water tank todisplace the water into the said column, a carbid holder removablyfitted within the upper portion of the float in alinement with thecolumn and a removable cap fastened to the contracted portion of thebell for closing the column and the said contracted portion.

2. A generator of the class described comprising an outer water tank, aninner water tank therein rising from its bottom, a gas bell workingbetween the outer and inner water tanks and having a contracted upperportion, a column rising from the top of the bell centrally within thecontracted portion, a water float depending from and centrally withinthe bell and working within the inner water tank to displace the waterinto the said column, a carbid holder removably fitted within the upperportion of the float in alinement with the column, a removable capfastened to the contracted portion of the bell for closing the columnand the said contracted portion, and a service pipe having a stretchthereof extended upwardly within the space between the inner and outerwater tanks.

In testimony whereof I aflix my signature in presence of two witnesses.
